BUILDI'IN'G-BLOCK,

To aZZIwhom it may concern:

Be it known that I,Lno SAJ6,Cli 1ZIl of the Kingdom of Hungary, and resident of Budapest, in the county of Pest-Pilis Solt- Kiskun, Austria-Hungary, have invented a certain new and useful Improved Buildin Block for Use in the Construction of Part1- tion-lvallsj'and Roofs, of which the following is a specification.

The present invention relates to building blocks.

One of the objects of the invention is to provide building blocks of uniform size, which can be arranged to produce partition walls or roof-coverings of varying dimensions. v 3

Another object of the invention is to provide building blocks, whereby a strong, durable, efficient and inexpensive partition wall may be produced.

A further object of the invention is to provide building blocks which will form partition walls of great strength and stability, and which will prove to a great extent impervious to heat and sound.

\Vith these and other objects in view, which will appear as the nature ofthe invention is better understood, the same consists in the combination, arrangement and construction of parts hereinafter fully described, pointed out'in the appended claims and illustrated in the accompanying drawings, it being understoodthat many changes may be made in the size and proportion of the several parts and minor details of construction without departing from the spirit or sacrificing any of the advantages of the invention.

One of the inany possible embodiments of the invention is,illustrated in the accompanying drawings, in which Figure l is a front elevation of a partition wall constructed of the building block forming the subject matter of the present application for Letters Patent; Fig. 2 is a front. elevation of one of the blocks; Fig. 3

is a rear elevation of the same; Fig. 4 a vside elevation thereof; Flg.

is a section takenon line AB and Fig. 6 is 'a section takem'on line C-D of Fig. 2; and Fig. 7 is a plan view of the innn-oved building block.

In the drawings, a substantially I'-shaped building block is shown, which comprises a Jase 3, a web 5 and a head 2. 'Jln-mxgh the base and head I Specification 01' Letters Patent. Patented luay 9', 1911.

entire width of the base and head and through the width of the web extend channels l, l; more particularly through the one channel,-while through the web lead two channels.- These channels are parallel to each other and are arranged equi-dis'tant-ly. so that, when a wall is fornn-d, continuous passagesv will be prgduced in the masonry.

The side surfaces (5, (S of the web 5 are inclined relative -to the faces of the and so are also the 'side surfaces 4, 4 of the base and head, '6r in other words those sides of the base and head, the edges of which are parallel tothe sides '6 of the web. The

- sides 4, 4 of the base and head are, however,

inclined in a direction opposite to that of the inclination of the sides 6 of the Web.

It should be noted that the combined height of the base and head of the building och corresponds to the height of the web, that is to say the recesses in the blocks are of such dimensions that each of the same is adapted to receive the base of one block and the head of another block, so that each horizontal row of blocks will support the next row below it.

In building the wall, the'building blocks are. engaged with each other in the manner shown in Fig. 1 of the drawings, whereby the inclined faces of one block will be engaged with those of the adjoining blocks to produce a wedging ctl'ect, which will allow a wall to be built without the employment of mortar or other eennniling agent. k If the above described blocks, are of a comparatively small thickness, and the channels 1, l omitted, the blocks can be used for the purpose of covering roots, in which arrangement; they will root construction for the reason that there are no overlapping portions or projecting bonds as in the usualrooling tile construction, heretofore in use.

iVhat I claim is:

l. A building block for partition walls, comprising a base, a head and a connecting web arranged to form a substantially I.- shapcd strmzture having channels leading throughout the width of said base and head and through the width of said web, the-side surfaces of said web being inclined relative to the face of the block, and the sides'of said base and said head the edges of which are parallel to the side surfaces of'said web block,

produce a lighter J a web -arranged being also inclined relative .to the face of the block in a direction opposite to the inclination of the side surfaces of said web.

' 2. A building block for partition-walls, comprising a base, aheadand a connecting to forma substantially I- shaped structure, the side surfaces of said web being inclined relative to the face of the block, and thesidesof said base and said head the edges of which are parallel to the side surfaces of said web being also inclined relative to the face of the block in a. direction opposite to the inclination of the side surfaces of said web.

3. A building block for comprising a base, web

partition walls, a head and a connecting arranged to form a substantially I- said base and head being equal to the height of said web, the side surfaces of said web being inclined relative to the face'of the block, and the sides of said base. and-said head the edges of which are parallel to the side surfaces of said web being also inclined relative to" the face-of the block in a direcr block in 4. A building block for partition walls,

comprising a base, a head and a connecting web-arranged to form a substantially I--' shaped structure having channels leadin throughout the width of said base and hea and through the width of said web, the combined hei ht of said base ing equal to t e height of said web, the side surfaces of said .web to the face of the block, base and parallel to the side surfaces of said 'web' being also and the sides of said inclined relative to the face of the Signed at Budapest, in the county of Pest- PilisSolt-Kiskun, Hungary this 24th day of December A. D. 1909.
